Hi! This is a small PR to allow to use the
filter_traces
function when tracing router events.I have an application where I need to have 2 endpoint (with their own router / controllers etc.). This is working very well with the endpoint telemetry events since my endpoint use different prefix (ex
[:phoenix, :endpoint, :my-endpoint]
) and I can pass theendpoint_telemetry_prefix
options to catch them properly.But for the router events, since I'm using
SpandexPhoenix.Telemetry.install/1
twice (one for each endpoint, with different options), I have duplicated traces.I'm not sure my PR is the right approach, it might be a good idea to allow to pass a new options to handle this but I figured that this would include minimal changes to the codebase and might be prefered for this.
Thanks for the great work on this project 😃 🙌
